Thomas McGahee's PICUART.ASM. You can find it here: http://www.pic101.com/mcgahee While you don't have to use it, the two things that it helps out with are: 1) It has a completely working tutorial program that you can just drop in and test with. 2) The fully annotated code with all of the PICUSART gotchas often will point out the item that you missed. I use it as component code for serial, since I know that it's been well tested and well documented. It just works.
